Aston Villa have completed the signing of 19 year old Barcelona winger Adama Traore for a fee reported to be around £7m.
"He's dynamic, very quick and a maverick-type player - you never know what he's going to do next and I mean that as a compliment," Villa manager Tim Sherwood told BBC WM 95.6.
"He's a huge asset for this club. He can hurt the opposition and I'm delighted to bring him here."
"He comes from a very good academy with Barcelona and I've known him a long time," added Sherwood.
"He makes his mind up when he gets the ball and those players are rare - there aren't many players in the Premier League that can do that.
"We're getting him at the midway part of his development, he's not the finished article by a long way but he can certainly help us out in the short-term and in the future."
